Tomahawk CNC – 4th Axis Rotary System (50:1 Precision Reduction)

Add true rotary machining capability to your CNC mill or router with the Tomahawk CNC 4th Axis Rotary System. Engineered for accuracy, rigidity, and repeatable workholding, this rotary axis features a 50:1 precision gear reduction, dramatically increasing positioning accuracy and holding torque—perfect for engraving, indexing, gear cutting, and full 4-axis contouring.

Driven by a 6 Nm closed-loop stepper motor, the system continuously monitors position and corrects missed steps automatically, ensuring reliable and consistent rotation under load. No lost motion, no guessing, no re-zeroing.

Multiple vise options are available to suit different materials and job requirements, including small profile jaws for fine work and a larger high-grip hobby vise for more demanding setups.
